FIELD OF THE INVENTION

The present invention relates to a system for recording and playback of electronic event sequence utilizing a distributed ledger. The system is typically configured for: monitoring a source system; recording data regarding the source system onto a distributed ledger, the data including event data regarding electronic events occurring within the source system; constructing, from the event data of the distributed ledger, a testing dataset including event data regarding simulated electronic events; and simulating, in a testing environment, the simulated electronic events using the testing dataset.

BACKGROUND

Many entities are required to routinely clone, copy or transfer data from one system to another and use the cloned system for coding, testing and/or quality assurance. However, due to sometimes excessively large and constantly growing data sources, system cloning is not performed as often as recommended due to data size and length transfer times. As a result, there exists a need for a new system restore and copy technology that overcomes the challenges of traditional system restore, data copy and/or cloning methods.

For example, an interaction may refer to a transfer of data between systems or devices, an accessing of stored data by one or more devices, a transmission of a requested task, a migration or backup off data between environments, or the like.

As used herein, an “electronic event” refers to any discrete event (or series of events) that may occur within an electronic system (e.g., any computer system or other electronic system operated by an entity). An electronic event may refer to the processing of an item (e.g., an electronic request or electronic file) by an electronic system. An electronic event may refer to any change to a database of an electronic system. In some instances, an electronic event may refer to the processing of a resource transfer or transaction. A “resource transfer” or “transaction”, may refer to any activities or communication between a customer (e.g., either an individual person or an organization) of an entity and the entity, activities or communication between multiple entities/customers, communication between technology applications and the like. A resource transfer may refer to a payment, processing of funds, processing of a check, purchase of goods or services, a return of goods or services, a payment transaction, a credit transaction, or other interactions involving a customer's resource or account. In the context of a financial institution or a resource entity such as a merchant, a resource transfer may refer to one or more of: a sale of goods and/or services, initiating an automated teller machine (ATM) or online banking session, an account balance inquiry, a rewards transfer, an account money transfer or withdrawal, opening a bank application on a customer's computer or mobile device, a customer accessing their e-wallet, or any other interaction involving the customer and/or the customer's device that invokes or is detectable by the financial institution. A resource transfer may include one or more of the following: renting, selling, and/or leasing goods and/or services (e.g., groceries, stamps, tickets, DVDs, vending machine items, and the like); making payments to creditors (e.g., paying monthly bills; paying federal, state, and/or local taxes; and the like); sending remittances; loading money onto stored value cards (SVCs) and/or prepaid cards; donating to charities; and/or the like. Unless specifically limited by the context, a “resource transfer” a “transaction”, “transaction event” or “point of transaction event” refers to any activity initiated between a customer and a resource entity such as a merchant, between the customer and the financial instruction, or any combination thereof. In some embodiments, a resource transfer or transaction may refer to financial transactions involving direct or indirect movement of funds through traditional paper transaction processing systems (e.g., paper check processing) or through electronic transaction processing systems. In this regard, resource transfers or transactions may refer to the customer initiating a purchase for a product, service, or the like from a merchant. Typical financial transactions include point of sale (POS) transactions, automated teller machine (ATM) transactions, person-to-person (P2P) transfers, internet transactions, online shopping, electronic funds transfers between accounts, transactions with a financial institution teller, personal checks, conducting purchases using loyalty/rewards points etc. When discussing that resource transfers or transactions are evaluated it could mean that the transaction has already occurred, is in the process of occurring or being processed, or it has yet to be processed/posted by one or more financial institutions. In some embodiments, an electronic event may refer to non-financial activities of the customer. In this regard, the transaction may be a customer account event, such as but not limited to the customer changing a password, ordering new checks, adding new accounts, opening new accounts, adding or modifying account parameters/restrictions, modifying a payee list associated with one or more accounts, setting up automatic payments, performing/modifying authentication procedures, and the like.

The term “distributed ledger,” as used herein, refers to a decentralized electronic ledger of data records which are authenticated by a federated consensus protocol. A distributed ledger may be a blockchain. Multiple computer systems within the distributed ledger, referred to herein as “nodes” or “compute nodes,” each comprise a copy of the entire ledger of records. Nodes may write a data “block” to the distributed ledger, the block comprising data regarding an electronic event, said blocks further comprising data and/or metadata. In some embodiments, only miner nodes may write electronic events to the distributed ledger. In other embodiments, all nodes have the ability to write to the distributed ledger. In some embodiments, the block may further comprise a time stamp and a pointer to the previous block in the chain (e.g., a “hash”). In some embodiments, the block may further comprise metadata indicating the node that was the originator of the electronic event. In this way, the entire record of electronic events is not dependent on a single database which may serve as a single point of failure; the distributed ledger will persist so long as the nodes on the distributed ledger persist.

A “block” as used herein may refer to one or more records of a file with each record comprising data for transmission to a server. In some embodiments, the term record may be used interchangeably with the term block to refer to one or more transactions or data within a file being transmitted. In particular, the distributed ledger (e.g., blockchain) begins with a genesis block and is subsequently lengthened by incrementally appending blocks in series to the genesis block. Generally, the data within each block within the distributed ledger may not be modified by the nodes of the distributed ledger; data may only be added through the addition of a block to the last block in the distributed ledger. Each block added to the distributed ledger may comprise a timestamp and a pointer to the previous block in the distributed ledger (e.g., a “hash”). In this way, the distributed ledger may provide an immutable record of data records over a period of time. In some embodiments, in order for a new block to be added to the distributed ledger, a pending data record may be proposed to be added to the distributed ledger. The nodes may then, via a “consensus algorithm” or “consensus mechanism,” come to a consensus as to the contents of the data in the distributed ledger. Once a consensus has been reached by the nodes that the pending data record is valid, the nodes append the data record to the last block in the distributed ledger. In this way, each node maintains a validated copy of the distributed ledger such that the distributed ledger may remain accessible even if one or more nodes become unavailable (e.g. a node is offline due to maintenance, malfunction, etc.) and may further account for divergence from the true copy of the distributed ledger which may occur at the node level (e.g. a copy of the distributed ledger on a particular node becomes invalid due to data corruption, malicious editing, and the like). In other words, the consensus mechanism ensures that, over time, each node hosts a copy of the distributed ledger that is consistent with the other nodes.

Embodiments of the invention as described herein may utilize one, several, or a combination (i.e. hybrid) of a number of different consensus algorithms to ensure the integrity of the data within the distributed ledger. In some embodiments, the consensus mechanism may be a “proof of work” (“PoW”) algorithm, in which the nodes perform a series of calculations to solve a cryptographic puzzle. For instance, in order to validate a pending data record, the nodes may be required to calculate a hash via a hash algorithm (e.g. SHA256) which satisfies certain conditions set by the system. Calculating a hash in this way may be referred to herein as “mining,” and thus a node performing the mining may be referred to as “miners” or “miner nodes.”

“Miner node” as used herein refers to a networked computer system or device that authenticates and verifies the integrity of pending transactions on the distributed ledger. The miner node ensures that the sum of the outputs of the transaction within the block matches the sum of the inputs. In some embodiments, a pending transaction may require validation by a threshold number of miner nodes. Once the threshold number of miners has validated the transaction, the block becomes an authenticated part of the distributed ledger. By using this method of validating transactions via a federated consensus mechanism, duplicate or erroneous transactions are prevented from becoming part of the accepted distributed ledger, thus reducing the risk of data record tampering and increasing the security of the transactions within the system.

Embodiments of the invention provide a technical solution to the problem of large-scale electronic event reconstruction by utilizing distributed ledger systems in a nonconventional way. Many entities routinely transfer data in a system from one system to another system, such as for creating a production copy for product development, testing and/or quality assurance. For example, potentials changes (e.g., software upgrades or updates or changes in settings) to a system are typically tested in a testing environment before such changes are implemented in a system. However, due to excessively large and constantly growing data sources, environment cloning is not performed as often as recommend due to data size requiring lengthy restore times. Currently, for database on the scale of several terabytes, traditional cloning method can take several days to weeks to create a system copy, as the entire database must be cloned for every performed migration even if only a portion of the database is of interest. Due to these excessive transfer times and computing resources that must be dedicated to the lengthy task, system cloning for large environments are sometime only performed once or twice a year. Challenges also exist in creating mock workloads that can be used in testing environments to test potential changes to systems. Typically such mock workloads are created manually, and are thus time consuming to create. Moreover, such mock workloads are typically not representative of all types of electronic events that may be processed by a production system, thus creating potential gaps in testing that may be performed.

The system and methods provided herein overcome these problems by provided a selective data recordation and reconstruction solution that utilizes and adapts distributed ledger technology to allow for faster, resource efficient data reconstruction providing the most recent copy of data needed for product development and/or data testing. A distributed ledger is used to record electronic events that occur within a source system/environment (e.g., a production system/environment). The distributed ledger may also be used to record other information about the source system, such as storing a copy of the source system's settings and software. The system typically modifies block headers of blocks storing data of the system on a distributed ledger to prequalify the data stored thereon allowing for a user to selectively clone only the data that the user desires from the source system distributed ledger. The system can define an endblock on which the data migration will cease so that the target system can be selectively restored over and over again by appending part of the distributed ledger to the previously restored blocks thereby eliminating a need to copy the entirety of the system every time a user wishes to migrate a portion of the system for testing, quality assurance, product development, or the like. Additionally, electronic events that occurred within the source system and recorded to the distributed ledged may be reconstructed and used for testing purposes, thereby facilitating more realistic testing. Furthermore, the system retains migrated portions of the system data allowing for the user to build additional copy tasks in the target environment without needing to recopy the previously copied data from the production system again. Furthermore, by modifying the block headers of the blocks on the distributed ledger to prequalify and sort data into categories, the system improves distributed ledger technology.

In other embodiments, the other entity systems 140 are distinct from the selective data recordation and reconstruction system 130. The selective data recordation and reconstruction system 130 may communicate with the other entity systems 140 via a secure connection generated for secure encrypted communications between the two systems.

In one embodiment of the selective data recordation and reconstruction system 130 the memory device 306 stores, but is not limited to, a selective data recordation and reconstruction application 312. In one embodiment of the invention, both the selective data recordation and reconstruction application 312 and/or the controller 301 may associate with applications having computer-executable program code that instructs the processing device 304 to operate the network communication device 302 to perform certain communication functions involving described herein. In one embodiment, the computer-executable program code of an application associated with the controller 301 and/or selective data recordation and reconstruction application 312 may also instruct the processing device 304 to perform certain logic, data processing, and data storing functions of the application.

In some embodiments, the controller 301 instructs the processing device 304 to execute data recordation and/or reconstruction from a system data storage 145 of the entity system 140 from a production environment to a non-production environment for testing, quality assurance, and/or product development.

FIG. 4A illustrates a centralized database architecture environment 400, in accordance with one embodiment of the present invention. The centralized database architecture comprises multiple nodes from one or more sources and converge into a centralized database. The system, in this embodiment, may generate a single centralized ledger for data received from the various nodes. FIG. 4B provides a general distributed ledger system environment architecture 450, in accordance with one embodiment of the present invention. Rather than utilizing a centralized database of data for instrument conversion, as discussed above in FIG. 4A, various embodiments of the invention may use a decentralized distributed ledger configuration or architecture as shown in FIG. 4B.

The distributed ledger may be a blockchain. A blockchain is a distributed database that maintains a list of data blocks, such as real-time resource availability associated with one or more accounts or the like, the security of which is enhanced by the distributed nature of the blockchain. A blockchain typically includes several nodes, which may be one or more systems, machines, computers, databases, data stores or the like operably connected with one another. In some cases, each of the nodes or multiple nodes are maintained by different entities. A blockchain typically works without a central repository or single administrator. One well-known application of a blockchain is the public ledger of transactions for cryptocurrencies. The data blocks recorded in the blockchain are enforced cryptographically and stored on the nodes of the blockchain.

A blockchain provides numerous advantages over traditional databases. A large number of nodes of a blockchain may reach a consensus regarding the validity of a transaction contained on the transaction ledger. As such, the status of the instrument and the resources associated therewith can be validated and cleared by one participant.

The blockchain system typically has two primary types of records. The first is the transactions, which consists of the actual data stored in the blockchain. The second is the block headers, which are records that confirm when and in what sequence certain transactions became recorded as part of the blockchain. Transactions are created by participants using the blockchain in its normal course of business, for example, when someone sends cryptocurrency to another person, and blocks are created by users known as “miners” who use specialized software/equipment to create blocks. In some embodiments, the blockchain system is closed, as such the number of miners in the current system are known and the system comprises primary sponsors that generate and create the new blocks of the system. As such, any block may be worked on by a primary sponsor. Users of the blockchain create transactions that are passed around to various nodes of the blockchain. A “valid” transaction is one that can be validated based on a set of rules that are defined by the particular system implementing the blockchain. For example, in the case of cryptocurrencies, a valid transaction is one that is digitally signed, spent from a valid digital wallet and, in some cases that meets other criteria.

As mentioned above and referring to FIG. 4B, a distributed ledger system 450 is typically decentralized—meaning that a distributed ledger 452 (i.e., a decentralized ledger) is maintained on multiple nodes 458 of the distributed ledger 450. One node in the distributed ledger may have a complete or partial copy of the entire ledger or set of transactions and/or blocks on the distributed ledger. Transactions are initiated at a node of a distributed ledger and communicated to the various nodes of the distributed ledger. Any of the nodes can validate a transaction, add the transaction to its copy of the distributed ledger, and/or broadcast the transaction, its validation (in the form of a block) and/or other data to other nodes. This other data may include time-stamping, such as is used in cryptocurrency distributed ledger. In some embodiments, the nodes 458 of the system might be financial institutions that function as gateways for other financial institutions. For example, a credit union might hold the account, but access the distributed system through a sponsor node.

Various other specific-purpose implementations of distributed ledger s have been developed. These include distributed domain name management, decentralized crowd-funding, synchronous/asynchronous communication, decentralized real-time ride sharing and even a general purpose deployment of decentralized applications. While the exemplary distributed ledger of FIG. 4B is discussed as recording records of transactions (i.e., cryptocurrency exchanges), it should be understood that other data may be stored on the block chain such as files, programming code, configuration files, or any other data type.

FIG. 5 provides a high level process flow illustrating node interaction within a distributed ledger system environment architecture 500, in accordance with one embodiment of the present invention. As illustrated and discussed above, the distributed ledger system may comprise at least one or more nodes used to generate blocks. The nodes as discussed with respect to FIG. 5 may be the nodes 120 of the system environment 100 discussed in FIG. 1. In some embodiments, the channel node 504, payments node 506, monitor node 516 or the clearing node 508 may publish a pending transaction 510 (or any interaction (e.g., file edit, migration, upload, or the like)) to the distributed ledger 502. At this stage, the transaction has not yet been validated by the miner node(s) 512, and the other nodes will delay executing their designated processes. The miner node 512 may be configured to detect a pending transaction 510. Upon verifying the integrity of the data in the pending transaction 510, the miner node 512 validates the transaction and adds the data as a transactional record 514, which is referred to as a block to the distributed ledger 502. Once a transaction has been authenticated in this manner, the nodes will consider the transactional record 514 to be valid and thereafter execute their designated processes accordingly. The transactional record 514 will provide information about the transaction processed and transmitted through and metadata coded therein for searchability of the transactional record 514 within a distributed ledger. In some embodiments, the system may comprise at least one additional miner node 512. The system may require that pending transactions 510 be validated by a plurality of miner nodes 512 before becoming authenticated blocks on the distributed ledger.

In some embodiments, the computer systems represent the nodes of the distributed ledger, such as the miner node 512 or the like. In such an embodiment, each of the computer systems comprise the distributed ledger, providing for decentralized access to the distributed ledger as well as the ability to use a consensus mechanism to verify the integrity of the data therein. In some embodiments, an upstream system and a downstream system are further operatively connected to the computer systems and each other through the network. The upstream system further comprises a ledger and the distributed ledger. The downstream system further comprises the distributed ledger and an internal ledger, which in turn comprises a copy of the ledger.

In some embodiments, a copy of distributed ledger may be stored on a durable storage medium within the computer systems or the upstream system or the downstream system. In some embodiments, the durable storage medium may be RAM. In some embodiments, the durable storage medium may be a hard drive or flash drive within the system.

FIG. 6 provides a process map for selectively migrating data blocks 600, in accordance with one embodiment of the invention. Initially, the system establishes a connection to a distributed ledger storing a distributed record of a database over a network (e.g., network 101). Data stored in the system or database may include files, transaction data, configuration data, programming code, or the like. In some embodiments, the distributed ledger is a parent distributed ledger operating within a source environment. In one embodiment, the source environment is a system (e.g., a production system) wherein software or another product is put into operation for intended use by end users. In one example, data is stored on a parent chain within a production system/environment, wherein the data is actively used software.

The system uniquely stores data within the blocks of the distributed ledger by bucketing or grouping the data into predefined data categories, wherein data of different data types may be distinguishable from one another by the system. Data types are distinguishable groupings or categories of like data. Different data types may include, for example, electronic event data, configuration data, software code, different file types, and the like. In a specific example of data types, a user's personal files may be grouped into different data types such as pictures, documents, videos, etc.

As illustrated in the block 602, the system is able to store and distinguish data of different data types from one another by modifying block headers of the blocks on a distributed ledger with separate hashes which are used to define data types of data stored therein and prequalify said data with distinguishable data types allowing for bucketing of data based on the data types. The system generates the separate data hashes and records them in the block header of each block. For example, as illustrated in embodiment of FIG. 8, each block is recorded with separate hashes (e.g., “PrevBlockHashA”) for each data type (i.e., data types A, B, and C) which appropriately groups and distinguishes data of each type from one another.

In some embodiments, the present system is configured to define any number of separate buckets for any number of data types. Buckets are predefined by the system and/or user before the distributed ledger is built. In contrast, conventional distributed ledger technology typically only employs a single hash for all data, wherein data of different data types is not separately bucketed. In one embodiment, the system may define a single bucket and hash, wherein the distributed ledger operates similar to a conventional distributed ledger coupled with the additional improvements described herein.

As illustrated in block 604, the system receives a migration request to selectively clone at least a section of the parent distributed ledger from the source environment. A migration request may include, an executed command to migrate, clone, or otherwise copy at least a portion of the parent distributed ledger (i.e., an incremental section of one or more blocks) from the source environment to a target environment. A target environment is an environment separate from the source environment. In one embodiment, a target environment may include a testing environment, a quality assurance environment, and/or a product development environment. In one embodiment, a migration request may be received by the system from a user via a user device. In another embodiment, migration requests may be scheduled to occur at regular time intervals (e.g., monthly, bi-weekly).

Following cloning of a section of the distributed ledger, as illustrated in block 606, the section is reconstructed in a second, child distributed ledger in the target environment. The reconstructed section of the parent distributed ledger is a copy of one or more incremental blocks from the parent block chain. In this way, the reconstructed section may be used as a restore point or a backup. In another embodiment, the reconstructed section may provide a code base with or without data for developing additional code within a testing environment. For example, in the illustrated embodiment of FIG. 7, the parent distributed ledger 710 comprises blocks A1-A12. The system builds a first restore 720 by cloning and reconstructing only blocks A1-A4 in the target environment to generate a second, child chain as defined by the system and/or user.

Boundaries of the copied and reconstructed section may be specifying by the system and/or user by, for example, defining a date, time, block number, hash or the like for which to limit the copy process. The system and/or user assigns an endblock value for the section to be copied, wherein the endblock value designates a maximum number of sequential blocks from the parent distributed ledger to be copied and reconstructed in the target environment (as seen in FIG. 9). The system may compare the assigned endblock value of the desired section to block header values of the blocks of the parent block chain to determine which blocks to copy to the target environment. For example, and endblock value of 3 may be assigned to the section to be reconstructed, wherein the system compares the endblock value of 3 to the block numbers of the blocks of the parent chain. The system determines blocks 1-3 are to be copied and reconstructed as the block numbers are less than or equal to the endblock value of 3. In one embodiment, an empty, blank, or “null” endblock value may indicate that no particular block range is specified and that all data on the distributed ledger is to be copied.

In another example, a user may specify a particular date and an endblock value for which to limit the data copy, wherein only the blocks in the parent block chain from the genesis of the distributed ledger to the particular date are copied and reconstructed in the target environment. Unlike conventional copy methods, the presenting system is able to selectively extract particular ranges of blocks containing the system data within the specified time range. In this way, a smaller, targeted data set may be copied as opposed to the entirety allowing for faster, more resource efficient data transfers.

As illustrated in block 608 of FIG. 6, the system may add one or more new, incremental blocks to the reconstructed section in the target environment thereby constructing a new block chain which differs from the parent distributed ledger in the source environment. The incremental blocks are added to the end of the reconstructed section. For example, in the first restore 720 illustrated in FIG. 7, new blocks B1-B3 are added onto the end of the section A1-A4 to create a new block chain. In one example, the new blocks may comprise new data, code, files, or configurations added into a portion of an existing program or file collection for product development within the target environment, wherein the target environment is a testing, quality assurance, and/or product development environment. In this way, the copied and reconstructed section with the new, incremental blocks may be a new or alternate version of a program or file collection.

As illustrated in block 610 of FIG. 6, the system may rebroadcast the one or more incremental blocks from the target environment back to the parent distributed ledger in the source environment. As the immutability of the record stored by the parent distributed ledger may not be corrupted, the one or more incremental blocks are added as new blocks on the end of the parent block chain. Further, in one embodiment, only the block content from the one or more incremental blocks are rebroadcast to the parent chain. The system generates a new block header (i.e., new hash) for incremental blocks rebroadcast and accepted to the parent block chain in order to properly refer to the previous blocks on the parent chain and maintain consistency of the record. In this way, a portion of newly developed or tested data from the target environment may be incorporated into the source environment (e.g., into production). For example, as illustrated in FIG. 7, incremental block B1 of the first restore 720 is rebroadcast to the parent chain 710 in the source environment where block B1 is added to the parent chain 710 as new block A9 to which additional blocks A10-A12 may be added.

Alternative, as illustrated in block 612, the system may trim the one or more incremental blocks from the new distributed ledger created in the target environment thereby restoring the section that was originally cloned and reconstructed in the target environment. After discarding the trimmed blocks in the target environment, additional incremental blocks may be added in their place. In this way, changes performed on the block chain in the target environment may be reverted which may be convenient in a testing or product development environment. In some embodiments, partially restored blocks with populated endblock values may be trimmed from the target environment to match the original distributed ledger.

In some embodiments, a second copy function may be performed by the system and/or user. The system and/or user may select a second section of the parent distributed ledger from the source environment and reconstruct the second section in the target environment. In some embodiments, the second section may comprise the first section already copied and reconstructed in the target environment. Instead of recopying the entirety of the first section while copying the second section, the system may utilize the already copied data of the first section in the target environment and only copy the remaining portions of the second section. The remaining portions of the second section are copied and added to the already copied first section in order to reconstruct the entirety of the requested second section by combining the parts in the target environment. In this way, the system does not need to recopy previously copied portions to the target environment and may conserve computing resources while reducing required data migration times.

Referring now back to FIG. 7, the exemplary embodiment illustrates a second restore 730 comprising blocks A1-A7 built in the target environment. The system builds the second restore 730 by only copying the remaining portion of the second restore (A5-A7) from the parent chain 710 and adding the remaining portion to the end of the blocks A1-A4 which were previously copied to construct the first restore 720. Similar to the first restore 720, the second restore 730 may have new, incremental blocks C1-C4 added to the end of the distributed ledger created in the second restore 730. Additionally, one or more of the incremental blocks C1-C4 may be rebroadcast back to the parent chain 710 similar to the process described with respect to the first restore 720. For example, in the illustrated embodiment, incremental block C3 is rebroadcast to the parent chain 710 in the source environment, wherein it is add to the end of the parent chain 710 as new block A12. Alternatively, one or more of the incremental blocks C1-C4 may be trimmed from the distributed ledger of the second restore 730, wherein the second restore 730 is returned to its original state from which additional incremental blocks may be added to create yet another version.

In another embodiment, endblock values may be assigned for different data types, wherein each endblock value designates a maximum block number to be copied and reconstructed for each separate data type. FIG. 8 provides a portion of a parent distributed ledger from which a second distributed ledger is reconstructed in FIG. 9 based on the rules defined by the block headers generated by the system. As illustrated in FIG. 8, the parent distributed ledger 800 comprises a number of sequential blocks comprising data stored as block content having three, separate data types A, B, and C which have been bucketed into three separate groupings according to the individual hashes of the modified block header. FIG. 9 illustrates an executed migration request defining endblock values of 3, 1, and 2 for data types A, B, and C, respectively. As illustrated in FIG. 9, data of type A is copied through block number 3, while copy of data of type B stops after block number 1 and copy of data of type C stops after block number 2. In this way, specific, targeted data may be selectively cloned and reconstructed in the target environment as opposed to traditional methods which would copy over the entirety of the data without bucketing by data type.

As described above, in one aspect, the present invention is directed to using a distributed ledger to record electronic events that occur within a source environment, such as a production environment, and then replaying those electronic events within a target environment, such as a testing environment. Replaying these recording electronic events within a testing environment facilitates more accurate testing of potential changes to the production environment.

FIG. 10 provides a process map for recording and playback of electronic event sequence utilizing a distributed ledger in accordance with an embodiment of the present invention. The process of FIG. 10 may be performed by the selective data recordation and reconstruction system 130.

Initially, at block 1002, the selective data recordation and reconstruction system 130 monitors a source (or other) system (e.g., a production system of the other entity systems 140).

At block 1004, the system 130 typically records data related to the source system onto a distributed ledger. This recorded data typically includes data related to electronic events that occur within the source system. In addition to event data, other types of data may be recorded as well. For example, information related to the software running within the source system (e.g., copies of the applicable software code) may be stored within the distributed ledger. Additionally, configuration data related to the source system (e.g., as contained in the system cache of the source system) may be stored within the distributed ledger. Further electronic events as well as information related to changes occurring within the source system (e.g., changes to the software or configuration of the source system) are stored over time in the distributed ledger, thereby facilitating the recreation of the current and past states of the system at any given time.

To distinguish between different types of data stored within the distributed ledger, block headers of the blocks of the distributed ledger may include separate hashes to define data types of data stored therein. Alternatively, the distributed ledger may be a parent distributed ledger that includes multiple child distributed ledgers, each of which includes data related to one data type.

In some embodiments, the system 130 may include a data capture manager that is configured to monitor and store system data within the distributed ledger. In some embodiments, the data capture manager/system 130 may be configured to modify system data before storing such data within the distributed ledger. For example, sensitive data from the source system may be redacted, masked, or replaced with mock data before such data is stored within the distributed ledger.

Next, at block 1006, the system 130 is typically configured to selectively clone a section of the distributed ledger and reconstruct such section of the distributed ledger in a testing environment. In particular, the system 130 is typically configured to recreate a current or previous state of the source system within the testing environment based on the data contained within the distributed ledger. For example, the system 130 may implement the current (or a previous version) of the product environment's software within the testing environment. By way of further example, the system 130 may implement the current configuration (or a prior configuration) of the source system within the testing environment. Cloning and reconstruction of data from the distributed ledger is described above in more detail. The system 130 may clone the current (or a previous version) of a database of the source system within the testing environment.

As part of this reconstruction, the system 130 may implement a potential change to the source system within the testing environment. For example, a potential update or upgrade to the source system software may be implementing within the testing environment and used for testing purposes prior to such update or upgrade being implemented within the source system. A potential change to the configuration of the source system may be implementing within the testing environment for testing purposes prior to such configuration change being implemented within the source system.

At block 1008, the system 130 typically constructs a testing dataset from the event data stored on the distributed ledger. In some embodiments, the testing dataset is created in the form of another distributed ledger. The testing dataset includes event data regarding simulated electronic events, which typically correspond to actual electronic events that occurred within the source system. Because the event data stored on the distributed ledger is based off actual electronic events that occurred within the source system, the simulated electronic events represented by the testing dataset accurately represent electronic events that occured within the source system (e.g., after a change to the source system has been implemented), thereby facilitating more accurate testing.

The system 130 typically includes a replay manager that is configured to construct the testing dataset. Typically, the testing dataset mirrors the data related to actual electronic events that occurred within the source system, and typically in the same sequence that the actual electronic events occurred. In some embodiments, the replay manager/system 130 may copy event data related to a prior time period to create the testing dataset. By way of example, if a change to the source system is scheduled to be implemented prior to a period of typically high-volume activity, the replay manager/system 130 may copy event data from a prior high-volume period to create the testing dataset. When creating the testing dataset, the replay manager/system 130 may be configured to scale the event data contained in the distributed ledger when creating the testing dataset. For example, if future expected activity within the source system is anticipated to increase tenfold (10×), the replay manager/system 130 may scale event data from a prior period by ten times (10×) to create the testing dataset. When creating the testing dataset, the replay manager/system 130 may also be configured to modify the event data contained within the distributed ledger. For example, the replay manager/system 130 may filter certain types of event data that may be not be applicable for testing. To the extent the event data in the distributed ledger contained redacted or masked data, the replay manager/system 130 may replace the redacted or masked data with mock data. Scaling of event data may be performed sequentially by repeating a series of events multiple times to achieve the desire scaling. Alternatively, scaling may be performed in parallel by repeating each discrete event multiple times before scaling the next event in sequence. For example, if events A, B, and C occurred in the source system and three fold scaling was performed, sequential scaling would result in a testing dataset having events A, B, C, A, B, C, A, B, and C, whereas parallel scaling would result in a testing dataset having events A, A, A, B, B, B, C, C, and C.

At block 1010, the system 130 (e.g., via its replay manager) simulates the simulated electronic events in the testing environment using the testing dataset. In some embodiments, the simulated electronic events are simulated substantially in real time with the creation of the data associated with such events by the replay manager (e.g., before the entire testing dataset is complete). In other embodiments, the replay manager creates the entire testing dataset before simulating the simulated electronic events. As part of this simulation, the simulated electronic events are typically processed using the current (or previous) software and/or configuration of the source system that has been implemented in the testing environment as described above (including potential changes to the same). Accordingly, potential changes to the software or configuration of the source system may first be tested in the testing environment prior to implementation in the source system. For example, a new version of the production software may first be tested in the testing environment by simulating the recorded electronic events. In addition, a software patch may first be testing in the testing environment (e.g., by simulating the recorded electronic events as described above) before being implemented in the source system.

In some embodiments, the system 130 may be configured to test multiple potential changes to the source system. In this regard, the simulated electronic events may be simulated in the testing environment to test the impact of a first change. Thereafter, a second change may be implemented in the testing environment and the simulated electronic events may be re-simulated to test the impact of the second change. This process may be repeated for additional potential changes to the source system. For example, different configurations may be testing to determine which configuration would be best to implement within the source system.
